175 parse-wormedit - Wormy level data parser
179 parse-wormedit [--format=<type>] [--levels=<number>] [--output=<file.ext>] <input.lvl>
183 Reads Wormy levels (either original WormEdit source or compiled TI-86 string)
184 from STDIN or given file, and prints parsed data to STDOUT.
186 If an I<output> file name is given, its extension determines the format,
187 otherwise explicitly given by the I<format> option:
193 Plain text summary of levelpack contents.
197 All parsed data in YAML syntax.
199 =item pnm, png, bmp, ...
201 Image drawing of rendered levels.
202 Unrecognised values are interpreted as file type and converted by Imager.
